This way the engine will run without JIT support. However, what to do with memory allocation functions like VirtualAlloc() that are only available on Windows? I mean to say, to run on embedded platforms, what alternate has to exist that may provide the facility of VirtualAlloc(). As far I have seen, the virtualAlloc() calls can be disabled even on Windows by setting HAVE_VIRTUAL_ALLOC to 0 in JSC/wtf/Platform.h. However, the garbage collection implementation uses this particular call inside JSC/runtime/Collector.cpp irrespective of HAVE_VIRTUAL_ALLOC being 0 or 1. Any suggestions on this front?
That call to VirtualAlloc is inside a PLATFORM(WIN_OS) guard -- you should not be hitting it on a non-windows platform
I have built Windows port with HAVE_VIRTUAL_ALLOC set to 0. But the VirtualAlloc() call inside JSC/runtime/Collector.cpp if replaced with fastMalloc() causes the WebKit to crash even on Windows.
This is basically expected -- as the code for other platforms should have also indicated the collector has important alignment requirements that fastMalloc does not guarantee.
I think to fix your issues you should work out why your platform is being reported as windows (PLATFORM(WIN_OS))
